Document Summary

Smooth muscle (food digestion and regulation of internal organs) Skeletal muscle (attached to bones, contraction enables bones to act as lever) Sarcomeres: contractile unit, arranged in series, 2 protein filaments (myosin, actin) A person must use muscles to work. Nutrients can be used to provide energy with oxygen (aerobic) or without oxygen (anaerobic) Energy required for muscle contraction comes from adenosine triphosphate (atp) and creatine phosphate (cp) - the energy carriers found in all cells. Nerve impulses (nap) on muscle (map) results in conversion of chemical energy (atp) to mechanical energy. Atp loses a phosphate to create energy. If not constantly replenished within cells, runs out within seconds during muscle contraction.
